Title: Exposing method
Inventor: SUZUKI AKIYOSHI
IPC: H01L21/027
Filed: 1985-01-12
Abstract: PURPOSE:To obtain the prescribed quantity of exposure stably without using a specific control means by repeating exposure based upon the pulse light of an excima laser plural times at every shot of the light. CONSTITUTION:Since the adjustment of the pulse oscillation time of the excima laser 1 is difficult but the output of the excima laser 1 can be adjusted, the output is reduced, the exposure value (output X pulse oscillation time) of each pulse is forecasted, the number of pulses is set up so that the sum of exposure values becomes the prescribed exposure value, and exposure is executed by plural pulses fixed at every shot. Respective exposure values of the sum which is forecasted to be the prescribed quantity of exposure can be optionally combined, i.e. respective exposure values to be forecasted may be set up equally or differently. When exposure is executed by 2 or more pulses at every shot, the probability (a) that the sum of the exposure values becomes 5% excess (the maximum value of said dispersion) is reduced as compared with the probability (b) of exposure executed only by one pulse at every shot.

Filed: 1986-01-14
Abstract: PURPOSE:To prevent the boiling of the fuel oil in an air separator by installing a heat exchanger for carrying out the heat exchange between the excessive fuel oil having a high temperature which is returned into the air separator and the low temperature fuel oil supplied into a fuel oil cleaner. CONSTITUTION:The excessive fuel oil which is not consumed in an internal-com bustion engine 10 out of the fuel oil heated to a high temperature by a secon dary fuel heater 9 is returned with high temperature into a heat exchanger 15. The high temperature fuel oil returned into the internal-combustion engine 10 is cooled by the heat exchange with the low temperature fuel oil supplied into a fuel oil cleaner 4 by a fuel oil feeding pump 2, and returned into an air separator 12.

Title: Method for detecting level of tank
Inventor: NAKAHARA TAKASHI
IPC: G01F23/14
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To detect level without being influenced by a change in the specific gravity of radioactivity or a fluid by a method wherein a gas is injected into an airtight tank in which a liquid from a constant-quantity-gas injection tank is contained and the level is computed on the basis of a change in the pressure of a gas-phase part inside the airtight tank. SOLUTION: A gas pipe 14 which supplies a gas G is connected to the upper pat (gas-phase part) of a waste-liquid tank 1, and a constant-quantity-gas injection tank 2 is connected to the other end of the pipe 14. Signals of a gas pressure before and after the injection of the gas in the gas-phase part in the waste-liquid tank 1 are input to a tank-level operating unit 16 from a waste-liquid-tank pressure gage 10. In addition, the signal of a set pressure inside the constant-quantity-gas injection tank 2 is input to the tank-level operating unit 16 from a constant-quantity-gas- injection-tank pressure gage 7. Then, in the tank-level operating unit 16, the volume in the liquid-phase part of the waste-liquid tank 1, i.e., the level of a waste liquid inside the waste-liquid tank 1, is computed. In this manner, by means of a change in the pressure in the gas-phase part of the airtight waste-liquid tank 1, the volume in the liquid phase of the waste-liquid tank 1, i.e., the level of the waste liquid inside the waste-liquid tank 1, can be detected.

Title: Infrared ray remote controller
Inventor: NISHIZAWA SEIJI
IPC: H04N5/00
Filed: 1993-01-14
Abstract: PURPOSE:To reduce a number of buttons by successively transmitting infrared ray codes, dealing with the operation using plural buttons, by means of only one key entry. CONSTITUTION:When a counter indicates one i.e., first a display button 5 is depressed, a code for turning on a VTR power source, a video code for switching VTR antenna, a television channel one code and a video confirmation display code are successively transmitted with a proper number of times and a proper interval, respectively. By transmitting various kinds of such transferring codes, the power source of a VTR is turned on, the antenna is changed over to the video side and the channel of a television becomes one. At this time, the input switch of the television is changed to a television channel side. If the display of confirmation does not appear on the television, the user depresses again the display button. Since the counter indicates two this time, the channel two code of the television is transmitted. When the high frequency output of the VTR is a channel two and inputted to the tuner input of the television, the display of confirmation appears similarly.

Title: Variable venturi carbureter
Inventor: NAGAI TOSHINARI
IPC: F02M3/05
Filed: 1982-01-18
Abstract: PURPOSE:To provide smooth control of a carbureter and quick rerise of a speed to an  expected value once a vehicle is accelerated during deceleration by placing the forward  and backward motion of a main nozzle into and from a barrel under negative pressure  control by use of the feature that a negative prssure in an intake manifold during deceleration is higher than an idling negative pressure and by gradually varying an air fuel ratio during deceleration by use of the feature of a delay of transmission of the  negative pressure. CONSTITUTION:When a vehicle is shifted from intermediate or high speed run S to deceleration run D, a throttle valve 4 is suddenly closed and a negative pressure V in an  intake manifold is thereby quickly increased from a ''L'' to a ''H''. A delay port 40 lets  the quickly increased negative pressure gradually transmitted into a negative pressure  chamber 37. When the negative pressure gets lower than an idling negative pressure, a  resiliently pushing spring 36 forces a diaphragm 34 to push a main jet 21 so that an  air fuel ratio A/F is gradually leaned to a ''L'', as shown by a curvd line l2, and then,  the fuel is finally cut at a point which is delayed by C' from an ordinary fuel cutting  point C. At this time, the vehicle is shifted from S to D, namely, an engine r.p.m. N is  reduced from the ''H'' to the ''L''. In short, after a needle 18 is shifted in association  with the closing motion of the valve 4, the main jet 21 is gradually pushed forward,  whereby discharged fuel is reduced and finally cut.
